Blending the power of two Kepler GPUs, the GeForce GTX 690 GPUs and a whopping 4GB of GDDR5 RAM is the fastest graphics card ever built by NVIDIA. It’s built from a combination of aluminium and magnesium alloys, and features a dual vapour chamber cooling system for quiet-yet-efficient airflow.
With 3,072 CUDA cores powering this beast, the GTX 690 delivers roughly the same performance as two GTX 680s. NVIDIA's Kepler GPU architecture has been designed from the ground up not just for maximum performance in the latest DirectX 11 games, but optimal performance per watt. The new SMX streaming multiprocessor is twice as efficient as the prior generation and the new geometry engine draws triangles twice as fast. The result is world class performance and the highest image quality in an elegant and power efficient graphics card.
Nvidia’s Turbo Boost technology remains intact, though, so that core clock will adjust up or down depending on how much work the GPUs are doing. Adjustments are made every millisecond, and the GTX 690's 915MHz core will hit a peak of 967MHz when it's at maximum load.
Aside from the clock drop, little of the GTX 680 has been changed. Each core is still accompanied by 2GB of 6,008MHz GDDR5 RAM, for a total of 4GB across the board. There have been no architectural changes, either, with the eight huge clusters serving each core still packing 192 stream processors each. Across the entire GTX 690, that means there are a mighty 3,072 stream processors and just over seven billion transistors.
NVIDIA Quad SLI® Technology3
Used by the most demanding gamers worldwide, Quad SLI lets you link up to two GeForce GTX 690s together for astounding performance. And with NVIDIA’s track record for fast and frequent software updates, you’ll not only get the best performance in existing games, but future games too.
